ELECTRIC MoTloN CONTROLLER.

SPECIFICATION formingpart of Letters Patent No. 412,529, dated October 8, 1889.

Application filed August 28, 1888. $erial No. 284,018. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAVE S. NEU, a citizen of the United States, residing in the 'city, county, and State of New York, have invented a new and useful Improvement in Electric Machinery Controllers, of which the following is a specification.

This invention relates to means for stop ping or starting running machinery through the agency of electricity otherwise than by stopping or starting the main driving-motor, so that, for example, in case an operator is caught in the machinery of a factory an observer could instantaneously stop that por- "tion of the machinery from an adjacent point without waiting until the main driver is stopped. i

The invention by which I attain this end consists, mainly, in the combination, with a belt-shifter, clutch, belt-tightener, or an equivalent gear-coupler arranged in the machinery between the main driver andthe machine or machines operated thereby, aweight, spring, or other reacting device adapted to operate the said gear-coupler, and a catch to restrain the gear-coupler, of an electricallywibratory catch-tripping hammer placed in an electric circuit extending to and provided with circuit-closers at the various points of the build ing whence the machinery may have to be controlled, whereby, when one of the circuitclosers is operated, the tripping of the catch and the operation of the gear-coupler by the reacting device will be rendered certain by the repetition of the blows of the trippinghammer.

In order that my invention may be fully understood, I will first describe in detail the manner in which it-may be carried into effect, and then point out its distinctive features in the claims.

Reference is to he had-to the accompanying drawings, forming part of this specification, in which- Figure 1 represents in elevation an electric machinery controller embodying my invention, a belt-shifter being used as the gearcoupler. Fig. 2 is a similar view of an electric machinery controller embodying my invent-ion, using a clutch as the gear-coupler.

an operatinglever O, which is pivoted to a fixed support D. The lever O has an arm 0, which is arranged to engage automatically the forked arm of a lever E, and the lever E to automatically engage and be restrained, together with the operating-lever G, by a catch F, substantially as described in an application for an automatic power-controller filed by me May 11, 1888, No. 273,624, in connection with the arm of the valve employed therein,

The operating-lever C is provided with a reacting device G, which may be a weight, as shown, a spring, or kindred device, so adj usted as to automatically swing the lever O, and thus operate the gear-coupler A when the lever O is free. The arrangement is, by preference, such that when the lever O is restrained by the catch'F through the medium of the forked lever E the pin on the lever C will be away from the outer end of the slot in the gear-coupler A, and the arm 0 of the lever 0 correspondingly elevated above the horizontal, as shown, so that the lever C, when released, will acquire a certain momentum before the strain of the gear-couplerA comes upon it, and when such strain is-incurred the weight G will be in its most effective portion, whereby the operation of the gear-coupler is assured.

An electrically-vibratory hammer H is ar-' ranged to, when operated, trip the catch F and permit the operation of the gear-coupler 9 5 A by the reacting device G, substantially as also described in my previous application before referred to.

An adjustable stop K is, by preference,

provided for regulating the degree of en- 1o;

gagement of the catch F with the forked lever E.

The vibratory hammer H, its actuating electro-magnet H the forked lever E, and the catch F may be arranged within a metallic case L, having a removable cover L, and, to-

gether with the lever C, insulated from the case L, as represented.

The forked lever E is, by preference, as in my previous application referred to, provided with a cam-arm E, to engage a yielding contact M, which is secured to an insulating-post M in the case L when the lever E is itself engaged by the catch F, and to be separated from said contact M when the forked lever E swings to release the operating-lever C.

The case L is shown provided with insulated bindingposts N N, electrically connected with the electro-magnet H and the yielding contact M, respectively, and with insulated binding-posts O O, electrically connected with the intermittent circuit-breaker of the electrically-vibratory hammer H and with the forked lever E, respectively.

The binding-posts N N are connected with the respective terminals of the battery P, and the posts 0 0 With the parallel circuit-wires Q Q, which are carried throughout the building to which the invention is to be applied.

The circuit-closer R is provided on the case L for testing the Working of the contrivance, and other circuit-closers R are located at the various points of the building whence the machinery may have to be controlled.

When any of the circuit-closers R R are operated, the hammer H is vibrated and its vibration continued until the circuit is broken by the release of the forked lever E, and thus the action of the gear-coupler is rendered certain.

I claim as new and desire to secure by Letters 1atent 1. In an electric machinery controller, the combination, with a gear-coupler, as specified, of a reacting device to operate the gear-coupler, a catch to restrain the gear-coupler, a v1- bratory hammer to trip the catch, and electro-magnetic devices to operate the hammer, substantially as described.

2. In a machinery controller, the combination, with a gear-coupler, as specified, of an arm to operate the gear-coupler, a reacting device to Work the said arm, a forked lever to engage said arm, a catch to engage the forked lever, and a catch -tripping device, substantially as described.

3. The combination, with a gear-coupler, of a reacting device, a pin-and-slot or equivalent loose operating connection between the gearcoupler and the reacting device, a catch to restrain the gear-coupler, and a catch-tripping device, substantially as described.

GUSTAVE NEU.
